4.9 LTC 4681, LTC 4682 Series Modules
for Ethernet Data Transmission
NOTE: Although the LTC 4681 and the LTC 4682 are
both transceivers, one of each type must be used to
create a working ethernet fiber optic link. It does not
matter which model is used at a particular side of a
configuration.
4.9.1 Indicators / Operation
1. Set Dip Switches as Follows:
a) Dip Switch 1: AUTO NEGOTIATE –
Recommended setting is UP. When active,
speed and twisted pair connection type (
mdi or
mdi-x ) is automatically sensed. When disabled,
a cross over cable must be used, and both ends
of the link must be fixed at the same speed and
duplex setting.
b) Dip Switch 2: SPEED – This setting applies only
when AUTO NEGOTIATE is disabled. This
setting forces the connection speed to either
10Mbps (UP position) or 100Mbps (DOWN
position). The recommended setting is 100Mbps.
c) Dip Switch 3: DUPLEX – This setting applies
only when AUTO NEGOTIATE is disabled.
This setting forces the connection type to either
half duplex (UP position) or full duplex (DOWN
position). The recommended setting is Full
Duplex.
2. The POWER LED illuminates when AC power
is applied to the unit.
3. The FIBER LINK LED illuminates when a valid
optical link is established.
4. The AUTO NEGOTIATE ON/OFF LED
illuminates to indicate that Dip Switch 1 is set to
AUTO NEGOTIATE mode.
5. The LED at the top left of the RJ-45 ethernet
connector illuminates GREEN when a valid
ethernet connection link is established.
6. The LED at the top right of the RJ-45 ethernet
connector illuminates GREEN to indicate a
100Mbps connection speed. If the LED illuminates
ORANGE, the connection speed is 10Mbps.
